\bf \cfrac{-7x^2}{\sqrt{6x-6}}\cdot \cfrac{\sqrt{6x-6}}{\sqrt{6x-6}}\implies \cfrac{-7x^2\sqrt{6x-6}}{\sqrt{(6x-6)^2}}\implies \cfrac{-7x^2\sqrt{6x-6}}{6x-6}

the idea being, getting rid of the pesky radical at the bottom, simply multiply it by something that'd raise it to the root, so it gets out :)

Write an equation in point-slope form of the line that passes through the point (5, 1) and has a slope of -3
bogdanovich [222]

Answer:

<h2>         y - 1 = -3(x - 5)</h2>

Step-by-step explanation:

An equation in point-slope form of the line that passes through the point (<em>x₁,y₁</em>) and has a slope of <em>m</em>:

y - y₁ = m(x - x₁)

m = -3

(5, 1)     ⇒       x₁ = 5,  y₁ = 1

Therefore:

y - 1 = -3(x - 5)

By using formula of h^2=p^2+b^2

h=20

p=x

b=10

Now,

p=root h^2-b^2

x=root 20^2-10^2

x=root 400-100

x=root 300

x= 10root3

What is the measure of angle X.<br> Enter your answer in the box.
Volgvan

Answer:

x=61

Step-by-step explanation:

The three angles of a triangle add to 180 degrees

37+82+x = 180

Combine like terms

119 +x = 180

Subtract 119 from each side

119-119 +x= 180-119

x = 61

7th GRADE MATH RATIOS HELP TIME ALMOST OUT
wariber [46]

Answer:

8, 40, 28.6, 40, 80, 36.6

Step-by-step explanation:

First find out what the ratio of tulips and roses is for each garden.

Ben: 40÷(4+1) = 8 so 8×4=32 and 8×1= 8

Ina: 40÷(2+5) =5.7 so 2×5.7=11.4 and 5×5.7= 28.6

Use these numbers accordingly.

Seems odd that there would be decimals in a problem like this, consult your teacher.
